Zvex - Fuzz Factory

Postby modman » 26 Jun 2007, 13:54

Now I'm so glad I can just post a link :D

Here's that incredible French project to make your own zvex Fuzz Fact. clone. And there's that Japanese page where you can still make out the values to compare them.

and I thought I had a schematic around, but will have to check and get back...

After I have written five nonsense-posts I can place a link to the schematic.

Man, you on fire!

Anyways, on topic here's a Fuzz Factory demostration video by the man himself.

Here's a schematic I drew up. Does it look right? It's based on an unreadable one I found somewhere in the Wired. It seems to match up with gut shots I've seen.

Hey Hey!
Isn't that a EH LPB (or screaming bird etc)bipolar boost in front of a Dallas Arbiter fuzz Face, with a slightly better output connection and a whole lot of extra controls???
And "he" says it is a completely original design on "his" website!
Hmmmmmmmmmmmmmmmm :shock:

Wow, man you are right. Classic booster driving a classic Ge Fuzz face with extra controls. Probably is true what he said -- that he thought it up one night at the kitchen table.

Prime example of how 'new' effects are made - block building, really. Still a great design and a great box: economical and efficient. But the low part count makes is very vulnerable for cloning....

great post,
keep it up

the great 'Fuzz Factory still up at Ampage thread'

exchanges between RG an VZEX are great reading

Anyway, I believe that all of the people who think that the super-secret circuits that *they* have come up with (or cobbled together from other stuff)are the keys to the kingdom are a little bit deluded. And yes, zach, I do get all wound up when someone copies my words and artwork. The difference is The Rules. For better or worse, we have an arbitrary set of Rules. The Rules say, "Artwork, images, and words are protected. Ideas, unless patented, are not."

zachary and others who get voluntary non-disclosure are very lucky guys. There aren't any Rules against disclosure, but through force of personality and appeal to others' ideas of fair play, they get non-disclosure. This is good, and we're all playing nice, as we should.

In any case, I believe it would not affect Z Vex sales any for the schemos to be posted. The people who would build them are not the people who buy them now. They're different sets of people. However, most boutique pedal makers were themselves builders once, and I think that makes the separation of builders and capitalizers harder for them to see, because they're themselves one of the few people who would tinker, build, then sell. It must make it seem like everyone is like them. Zachary is not by any means the only boutique maker that this discussion applies to, just the one we see here. Many of use remember Mike Fuller's net-rage when his Fulldrive modification of the TS-9 was traced out.

So - I think the posting or not posting issue is overblown, but being an emotional issue will not go away.

Hi Lexx,
Yes, i forgot that one - one of my personal favourites too :D
I have a small quantity of OC81 transistors left from the 60s - okay i know they are not the fabled OC81D type, but my recollection was that the D type were designed for output stages and were fitted with a heatsink enclosing the OC81.
Anyway they do sound nice and can instantly transport you back to early Yardbirds days. :D
Cheers

well, he has both. dunno... i don't have the record. is that the rhythmean (meen?) album? cuz if it is, my stuff isn't on there. he bought about 25 of my effects during the tour supporting that record, but he had never seen them before that. i invented the fuzz factory at 5:00 am on saturday november 25, 1995. i met him almost exactly a year later while he was on the preliminary tour (small venues) for the record and he wanted christmas presents for all the people who had helped him with the record. he had bought up all the stock at a couple of my dealers already... his secretary denise contacted me with addresses and i ended up mailing a pile of those pedals to his friends directly with little notes saying "from billy" in my handwriting. wacky. his purchase made it possible for me to escape a storefront i lived in during the middle of that subzero winter. the furnace was going out in that place and it was in the forties at night indoors. my hands were so cold that i couldn't even pick up an eighth-watt resistor. thanks, billy. saved my butt. nice guy, too. skinny as a fishing rod. i saw his eyes once through those dark sunglasses when the light was just right.... very scary. he gave me a bunch of tickets and backstage passes for the show, and we had dinner after his concert, late night pizza. he wanted me find him a perkin's, but i convinced him that pizza was a better bet... he ate most of a large by himself. consumed a dozen diet cokes. and you'd think he would have had one of those lumps like a snake gets when it eats a kitten, but nope. nothin. we talked about pickups and pedals and he had this magician with him doing card tricks at the table, a vegas guy, who had built some magic tricks for one of billy's tours years before, and we talked about the trapdoors and chutes and smoke and poor dusty screaming bloody murder every time he had to do this falling stunt. all the time billy was eyeing this girl behind the counter, she couldn't have been more than 18, a punker with a million piercings and tattoos, but nice looking. when he left the place i stayed for a bit to talk to some friends, and told her as i left that billy gibbons had remarked that she was good looking. her knees buckled... she gasped, "i thought that was him! but i... i... i already have a boyfriend!" cripes. she probably only knew him from "legs". i guess rock and roll will never die. it'll just get wrinkly. really really wrinkly.
oops, was that off topic? i hate a chatty bbs. heh.

it's easy to see why pedals are so fun for guitarists.
they are small, underfoot (rackmount stuff has to be kicked if you are playing with both hands... as well it should be), they can be rearranged at will to create new interactions... they are easy to eliminate from your signal chain, easy to trade, sell, loan, hide, or hand to a repairperson for diagnosis (while the rest of your gear remains intact), can be tucked into a guitar case, pocket, or bag... and make your system flexible and understandable.
goshdarnit, stompboxes will always be around.
invent one today. think of the future! some kid is gonna need that thing. blow your own mind first, the rest will follow. and pray for the future of that bizarre yet eternal hope, the carbon-zinc nine-volt battery.

Hi AG
Now now, don't get bitter :wink:
This is a great site, and your excerpts make fun reading.
No one here disputes your knowledge or intelligence, lets just stay on task on this forum and leave judgement to the Big Guy (or Gal) upstairs.
Peace and Love

hi guru,

Fascinating reading, but what is that, Jack's personal notepad from the forum? Of course, you are right, but don't get too hung up zv. He just did everything he could to protect his business including lying and misleading people.

What is sadder is that this censorship is maintained and but not supported by the older members (RG, Jack, Gus, TG, Doug H, ....) who don't agree with it at all. Still Aron decides, and since his forum has become a worldwide diy stompbox platform, they just stick to the rules out of courtesy. That is ok.

But it is creating a misleading atmosphere on the board where newbies are unwillingly brought up in the myth of absolute orginality and mojo, though of course there is very little of that in stompbox making. Thanks for showing some early patents. If there is a patent that still only means you cannot commercialize the idea, but you can apply it for personal use.

In his own kind way, Aron communicated very vaguely about these matters in the courtesy of not wanting to name people. In the 'Since when did it become bad...' thread he starts out saying, "this is not directed at you, x" which it wasn't, it was xx. It was about posting an unverified layout made from an unverified schematic that coudn't be linked to on the board because of the censorship rules. In this thread Aron starts out promoting publishing schematics (except the known friends of course...) which indeed is the right thing to do...

There should at least be a clear list of what is forbidden, so we can keep updating! :lol:
BTW, what made the SHO an exception to the rule?

Mr. Zvex himself.... He wanted to proof, that the cloners make better stompboxes than he himself. Have a look:

From this I drew my first SHO-schematic, long before I found the japanese site. Thanks Zakki....

Sorry about the giant pic of the schaltplan. :oops:
But, as you can see, there's nothing fancy happening there. I have a fuzz I call the Shizzle which is pretty much the same concept of a Rangemaster boosting a Fuzz Face (I got the idea when I used my Rangemaster to boost my Fuzz Face and it sounded great.... suprised?). Anyway, though they are similar, I came up with mine well before I had any knowledge of the Fuzz Factory, and my fuzz has a COMPLETELY different set of controls and likely a completely different tone. I believe comparing the Fuzz Factory to the Shizzle does much to show the difference of my design philosophy compared to that of ZVex. I would like to post my schaltplan for the Shizzle so everyone knows what I'm talking about, but I'm afraid I can't reveal all the component values...... someone has to buy one and trace it out if they want to know that stuff :wink: . I'm not into "secrets", but I'd like to at least sell a few before the whole world knows how it works.......

Yeah, I'll post the schematic for the Shizzle - I'll just leave a couple little things out.... you'd still be able to build it, it just won't sound exactly like the one I sell. I'm sure a savvy builder could make it do whatever he/she wants.

Hi soulsonic
I had the same experience (plugged my germanium rangemaster into a fuzz face clone - it gives a great sound :D )
hey, i might even post my Hot Cake variation too :lol:
Good luck with your pedal sales, and thanks for sharing mate 8)
